Commercial Excellence

The rapid expansion of the Datacentre sector is transforming the industrial landscape and is a major growth area for our Electric Thermal Solutions (ETS) Business. Datacentres underpin the digital economy, supporting everything from cloud computing to AI-driven applications. ICF, a global consulting and technology firm, predicts that by 2030 up to 25% of USA power production could be consumed by AI datacentres and related industries, reflecting a dramatic surge in electricity demand.

Investment trends reinforce this momentum. For the first time, more capital is being invested in building datacentres than in the Oil & Gas sector, marking a significant shift in global priorities. This growth is not limited to technology giants; other industries, such as Banking, are also investing heavily in datacentres for AI-driven applications.

The expansion of the Datacentre sector drives demand for supporting products and services, such as industrial heaters, heat trace systems and transmission and distribution (T&D) equipment. We have seen related business, such as T&D equipment for key OEMs, grow by double digits, demonstrating the potential in this sector.

ETS’ collaboration with a leading global OEM is one example of our ability to drive growth from having a clear sector focus and an adaptable approach to meeting customer needs, supported by our differentiated engineering capability. Our customer required a bespoke heating solution for liquid-cooled load banks used in Datacentre commissioning, an application where thermal dissipation of the electrical load is critical.

Datacentres house large servers and electronic equipment, along with their associated cooling systems. Liquid-cooled load banks are essential devices used to simulate electrical loads to test and validate the performance of power systems, such as generators, uninterruptible power supplies and datacentre infrastructure. These tests generate significant amounts of heat, which must be effectively dissipated to ensure accurate and reliable results.

Within ETS, our North America Sales team collaborated with the Design Engineering teams at our Nuevo Laredo facility in Mexico to develop a heater prototype, leveraging Chromalox technology and cross-functional expertise. The result was a custom product that converts electrical load into heat, efficiently removed by a high-volume propylene-glycol mixture to optimise cooling.

Operational Excellence was key to customer service and delivery. During 2025, daily shipments of the heater increased by 75%. To meet this increasing customer demand, we leveraged our new Operational Excellence Framework to introduce ‘self-directed’ teams, lean workflows and to set up a dedicated production line.

The team at ETS adopted a partnership approach, delivering a bespoke solution that has customer insights and collaboration at its core, demonstrated through regular site visits and rapid set-up of production with continuous improvement. For example, by proposing to deliver fully assembled, hydro-tested tanks with heaters that reduced our customer’s labour and quality risks, we reinforced our position as a strategic partner.

As the Datacentre sector continues to expand globally, ETS’ blend of Commercial Excellence, through our sector focus and solution-sales, as well as Operational Excellence, through scalable, lean manufacturing, positions Spirax Group as a trusted partner for customers seeking reliable, innovative solutions in a fast-evolving market.
